DD's pursuit of 172 was given a severe blow when the Chawla (4/32) claimed three wickets—Kedar Jadhav, Yuvraj Singh and JP Duminy—in two overs to reduce them to 111-5 in the 16th over as the visitors could never recover from the blow and were restricted to 158/6.

This was DD's seventh loss of the season as they slipped to seventh position in the eighth team table with eight points from 11 matches and their hopes to qualify for the last four is all but over.

With a second successive win at home, KKR (13 points), on the other hand, brightened their playoff hopes as they jumped past Royal Challengers Bangalore to occupy third place.

Earlier, Yusuf Pathan once again held KKR's innings together with his 42 off 24 balls (3x4, 3x6) before Johan Botha blasted 17 from five balls (4x4) in the last over to lift them to a fighting 171/7.

Playing with an extra bowler after Sunil Narine got a clearance from the Board with a final warning, a relieved KKR re-jigged their batting order and sent Chawla at No 4 and the leg-spinner contributed with an useful 22 from 19 balls.

Required to score at 8.6 in pursuit of 172, DD promoted Manoj Tiwary to open the innings but the local lad failed to deliver.

Even as Shreyas Iyer (40) looked at ease at the other end, Tiwary played as many as 15 dot balls during his painful 28-ball stay and by the time he departed after Chawla gave the first breakthrough, the run-rate had shot up to 10.80.

It also meant that Iyer, who looked fluent with 40 from 34 balls with three fours and two sixes, panicked at the other end before being foxed by Hogg's guile and dragged the ball onto his off-stump.

Iyer looked impressive in his fifth 40 score—the first from an uncapped player—but Tiwary's pathetic innings triggered DD's slow downfall as KKR tightened the noose with their battery of spinners.
